The y-ray spectrum from the radiative capture of thermal neutrons in 96.83 % enriched 151Eu has been investigated in the energy range 150 keV to 880 keV using a Ge(Li) detector in Compton suppression technique. The structure of the spectrum was found to be extremely complex. 273 full-energy peaks have been resolved in the energy interval studied. The data are believed to provide a useful contribution to the still unsettled problem of constructing a reliable transition diagram for the odd nucleus 152Eu.

“…This type of method has already been applied into treatment of the excited states in odd-A nuclei by supposing spherical [12][13][14] or deformed [15] shapes. However, as an attempt to give a new description to the structure of the level scheme in a transitional nucleus, we have limited our study to a simple case where a microscopic picture is considered for the quadrupole phonon by means of Tamm-Dancoff Approximation (TDA) [16].…”

A quasiparticle-phonon coupling based on one quadrupole phonon is developed. The coupling is constructed by using a deformed average field of Nilsson, a monopole pairing interaction and a quadrupolequadrupole force. Microscopic structure of the quadrupole phonon is given from the Tamm-Dancoff Approximation. The two effects of recoil and Coriolis forces are included with the assumption of a symmetric rotational motion. Since theoretical treatment is performed for an odd-A nuclei the configuration of intrinsic states should contain both one-quasiparticle and quasiparticle-phonon components. This method is applied to describe the level scheme of 133 Nd for which an agreement with experimental data is obtained. The results are also found similar to previous calculations obtained by the Particle plus Triaxial Rotor Model.

The level structure of 16BEr and the de-excitation mechanism in this nucleus have been studied by radiative capture of thermal neutrons in sampies of natural erbium which give a cross-section contribution of 89.8±2.3 % for 167Er. Interference from the 9.q=2.1 %capture contribution of 166Er was welI known from aseparate study with enriched 166Er sampies. Highresolution measurements of they-ray spectrum have been performed using the Karlsruhe Ge(Li) anti-Compton spectrometer below 2 MeV and a Ge(Li) double-escape spectrometer above 5.
